Abstract

PURPOSE:To ease construction by juxtaposing box-like concrete blocks with bottom holes, in which an intermediate wall is provided between front and rear walls, to be filled with stones, etc., and then heaping up concrete blocks having the same structure on the box-like concrete blocks in order between the front and intermediate walls of the lower stage. CONSTITUTION:A concrete block (a) is provided in which front, intermediate, and rear walls 2, 3, and 4 are standingly provided on a base plate 1 having opening parts 10. Next the concrete blocks (a) are juxtaposed, and concrete and stones, etc., are placed in their insides. Then a concrete block (b) is provided which has the same structure and in which the depth between front and rear walls 2' and 4' is equivalent to the distance between the front and intermediate walls 2 and 3. After that the block (b) is heaped up on the block (a) with the front walls 2 and 2' made to have the same plane, and a weight part is placed in the inside. Moreover the same work is repeated to form a retaining wall having a stage-like soil-pressure receiving part 8. This permits lightened and simple carrying and construction, and the easy manufacture of a forming mold.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 3] The present invention relates to a method for forming a concrete block retaining wall of a weight-adding type that is large and tall and can withstand strong earth pressure.

[Problems to be solved by conventional technology and invention]

Recently, large retaining wall blocks have come into widespread use,
The larger the size, the greater the strength required.

If the wall thickness is increased to meet the required strength, it will inevitably become very heavy, making it difficult to carry and handle, making construction that much more difficult.

The present invention provides a method for forming a weight-adding type concrete block retaining wall that solves this problem.

[Means to solve the problem]

The present invention will now be described in detail with reference to the accompanying drawings.

A front wall 2 is placed at the front of the base plate 1, a middle wall 3 is placed behind the front wall 2 at a position supporting the back wall 4' of the blocks to be stacked on the upper stage, and a predetermined portion is attached from the middle wall 3 at the rear of the middle wall 3. Concrete blocks a with rear walls 4 erected are placed side by side at a weight addition interval l of and add weight to form 8 rows of concrete blocks, and on these 8 rows of concrete blocks, the front wall 2 degrees overlaps the front wall 2 of the concrete block a below, and the middle wall 3
A rear wall 4' stands erected behind the concrete block A and has a depth such that it can be placed on the inner wall 3 of the concrete block a below, and concrete pouring openings 10 are provided in the base plate 1 of the front space 5 and the rear space 6, respectively. Concrete blocks B provided with are placed and arranged in parallel, and weight is added in the same manner as described above to form 5 rows of concrete blocks. A weight-adding type concrete block characterized by forming a tall stacked front wall 7 on the front side and forming a stepped earth pressure receiving part 8 on the rear side to form a concrete block retaining wall that can withstand strong earth pressure. This relates to the method of forming retaining walls.

[For production]

A foundation is made on site, concrete blocks a made in a factory are placed side by side on the foundation 9, and concrete is poured into the front space 5 and the rear space 6, or concrete is filled with blocks of stone etc. Either pour it or fill it with stone blocks, concrete blocks, etc.

Concrete block b is placed and placed on top of it, and weight is added in the same way.

When this process is repeated and concrete blocks C row and concrete block D row are piled up, the upper and lower concrete blocks are joined together by the respective concrete pouring openings 10, and the stacking front wall 7 is erected on the front side.
An earth pressure receiving part 8 is formed in a stepped manner on the rear side, and this upper pressure receiving part 8
Due to the presence of this material, a concrete block retaining wall using a weight-adding method that can withstand strong earth pressure is created.

〔Example〕

In Fig. 1.2, concrete is poured into each of the front space 5 and the rear space 6 to add weight, while Fig. 3.4 shows the case where masonry is placed in the rear space 6.

As shown in FIG. 2, a side wall 11 having a concrete pouring opening 10 may be provided, or as shown in FIG. 4, it may be formed in the shape of a U-shaped groove without a side wall.

The base plate 1 is provided with uneven engagement steps 12 and 13 that engage with the tops of the lower front wall 2 and middle wall 3.

The concrete block f at the top level does not have an inner wall 3, and the inner walls 3 are present in blocks a to e.

Although the drawing shows a case of six stages, the number of stages may be smaller or larger.

A concrete pouring opening 10 is not provided in the outer side wall of the product located at the extreme end and in the base plate 1 at the lowest stage.

When connecting adjacent side walls, a bolt/nut method is preferable.

〔Effect of the invention〕

The present invention mass-produces concrete block bodies by mold production in a factory, transports them to the site, sets them side by side, and pours concrete to form a completed concrete block body.
Since the space is rectangular, it is possible to pull out the mold upward, making it easy to produce the mold in a factory.

Then, concrete is poured on site to integrate the upper and lower multi-level concrete block rows and add weight, but since the lower part becomes a large and stable retaining wall, it is a weight-adding concrete that can withstand strong earth pressure. This method is used to form block retaining walls.
